Electric Shock Prevention

Fire Prevention

Injury Prevention

Additional Instructions The following instructions must be also followed. If the product is handled incorrectly, it may cause unexpected fault, an injury, or an electric shock.

Safety Instructions Do not attempt to install, operate, maintain or inspect the product until you have read through this Instruction Manual and appended documents carefully and can use the equipment correctly. Do not use this product until you have a full knowledge of the equipment, safety information and instructions. Installation, operation, maintenance and inspection must be performed by qualified personnel. Here, an expert means a person who meets all the conditions below. A person who took a proper engineering training. Such training may be available at your local Mitsubishi Electric office. Contact your local sales office for schedules and locations. A person who can access operating manuals for the protective devices (e.g. light curtain) connected to the safety control system. A person who has read and familiarized himself/herself with the manuals.

In this Instruction Manual, the safety instruction levels are classified into "WARNING" and "CAUTION"

Incorrect handling may cause hazardous conditions, resulting in death or severe injury. Incorrect handling may cause hazardous conditions, resulting in medium or slight injury, or may cause only material damage.

Note that even the level may even lead to a serious consequence according to conditions. Be sure to follow the instructions of both levels as they are critical to personal safety.

WARNING While the inverter power is ON, do not remove the front cover or

the wiring cover. Do not run the inverter with the front cover or the wiring cover removed, as accidental contact with exposed high-voltage terminals and internal components may occur, resulting in an electrical shock. Even if power is OFF, do not remove the front cover except for

wiring or periodic inspection. You may accidentally touch the charged inverter circuits and get an electric shock. Before wiring or inspection, power lamp must be switched OFF.

Any person who is involved in wiring or inspection shall wait for at least 10 minutes after the power supply has been switched OFF and check that there are no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power OFF, and it is dangerous. This inverter must be earthed (grounded). Earthing (grounding)

must conform to the requirements of national and local safety regulations and electrical code (NEC section 250, IEC 61140 class 1 and other applicable standards). Any person who is involved in wiring or inspection of this

equipment shall be fully competent to do the work. The inverter must be installed before wiring. Otherwise you may

get an electric shock or be injured. Setting dial and key operations must be performed with dry

hands to prevent an electric shock. Otherwise you may get an electric shock. Do not subject the cables to scratches, excessive stress, heavy

loads or pinching. Doing so may cause an electric shock. Do not change the cooling fan while power is ON. It is dangerous

to change the cooling fan while power is ON. Do not touch the printed circuit board or handle the cables with

wet hands. Doing so may cause an electric shock. A PM motor is a synchronous motor with high-performance

magnets embedded in the rotor. Motor terminals holds high- voltage while the motor is running even after the inverter power is turned OFF. Before wiring or inspection, the motor must be confirmed to be stopped. In an application, such as fan and blower, where the motor is driven by the load, a low-voltage manual motor starter must be connected at the inverter's output side, and wiring and inspection must be performed while the motor starter is open. Otherwise you may get an electric shock.

WARNING

CAUTION

CAUTION

CAUTION Inverter must be installed on a nonflammable wall without holes

(so that nobody touches the inverter heat sink on the rear side, etc.). Mounting it to or near flammable material may cause a fire. If the inverter has become faulty, the inverter power must be

switched OFF. A continuous flow of large current may cause a fire. Be sure to perform daily and periodic inspections as specified in

the Instruction Manual. If a product is used without any inspection, a burst, breakage, or a fire may occur.

CAUTION The voltage applied to each terminal must be the ones specified

in the Instruction Manual. Otherwise an explosion or damage may occur. The cables must be connected to the correct terminals.

Otherwise an explosion or damage may occur. The polarity (+ and -) must be correct. Otherwise burst, damage,

etc. may occur. While power is ON or for some time after power-OFF, do not

touch the inverter as it will be extremely hot. Touching these devices may cause a burn.

CAUTION Transportation and installation Any person who is opening a package using a sharp object,

such as a knife and cutter, must wear gloves to prevent injuries caused by the edge of the sharp object. The product must be transported in correct method that

corresponds to the weight. Failure to do so may lead to injuries. Do not stand or rest heavy objects on the product. Do not stack the boxes containing inverters higher than the

number recommended. When carrying the inverter, do not hold it by the front cover; it

may fall off or fail. During installation, caution must be taken not to drop the inverter

as doing so may cause injuries. The product must be installed on the surface that withstands the

weight of the inverter. Do not install the product on a hot surface. The mounting orientation of the inverter must be correct. The inverter must be installed on a strong surface securely with

screws so that it will not drop. Do not install or operate the inverter if it is damaged or has parts

missing. Foreign conductive objects must be prevented from entering the

inverter. That includes screws and metal fragments or other flammable substance such as oil. As the inverter is a precision instrument, do not drop or subject it

to impact. The surrounding air temperature for LD models must be

between -10 and +50C (non-freezing). The surrounding air temperature for SLD (initial setting) models must be between -10 and +40C (non-freezing). Otherwise the inverter may be damaged. The ambient humidity must be 95%RH or less (non-

condensing). Otherwise the inverter may be damaged. (Refer to page 17 for details.)

Safety Instructions 1

CAUTION Transportation and installation The storage temperature (applicable for a short time, e.g. during

transit) must be between -20 and +65C. Otherwise the inverter may be damaged. The inverter must be used indoors (without corrosive gas,

flammable gas, oil mist, dust and dirt etc.) Otherwise the inverter may be damaged. This product must be used at an altitude of 2500 m or less, with

2.9 m/s2 or less vibration at 10 to 55 Hz (directions of X, Y, Z axes). Otherwise the product may be damaged. (For installation at an altitude above 1000 m, consider a 3% reduction in the rated current per 500 m increase in altitude.) If halogen-based materials (fluorine, chlorine, bromine, iodine,

etc.) infiltrate into a Mitsubishi Electric product, the product will be damaged. Halogen-based materials are often included in fumigant, which is used to sterilize or disinfest wooden packages. When packaging, prevent residual fumigant components from being infiltrated into Mitsubishi Electric products, or use an alternative sterilization or disinfection method (heat disinfection, etc.) for packaging. Sterilization of disinfection of wooden package should also be performed before packaging the product.

Wiring Do not install a power factor correction capacitor or surge

suppressor/capacitor type filter on the inverter output side. These devices on the inverter output side may be overheated or burn out. The output side terminals (terminals U, V, and W) must be

connected correctly. Otherwise the motor will rotate inversely. PM motor terminals (U, V, W) hold high-voltage while the PM

motor is running even after the power is turned OFF. Before wiring, the PM motor must be confirmed to be stopped. Otherwise you may get an electric shock. Never connect a PM motor to the commercial power supply.

Applying the commercial power supply to input terminals (U, V, W) of a PM motor will burn the PM motor. The PM motor must be connected with the output terminals (U, V, W) of the inverter.

Trial run Before starting operation, each parameter must be confirmed

and adjusted. A failure to do so may cause some machines to make unexpected motions.

WARNING Usage Everyone must stay away from the equipment when the retry

function is set as it will restart suddenly after a trip. Since pressing the STOP/RESET key may not stop output

depending on the function setting status, separate circuit and switch that make an emergency stop (power OFF, mechanical brake operation for emergency stop, etc.) must be provided. OFF status of the start signal must be confirmed before resetting

the inverter fault. Resetting inverter fault with the start signal ON restarts the motor suddenly. Do not use a PM motor for an application where the PM motor is

driven by its load and runs at a speed higher than the maximum motor speed. Use this inverter only with three-phase induction motors or with a

PM motor. Connection of any other electrical equipment to the inverter output may damage the equipment. Do not modify the equipment. Do not perform parts removal which is not instructed in this

manual. Doing so may lead to fault or damage of the product.

CAUTION Usage The electronic thermal relay function does not guarantee

protection of the motor from overheating. It is recommended to install both an external thermal and PTC thermistor for overheat protection. Do not use a magnetic contactor on the inverter input for

frequent starting/stopping of the inverter. Doing so may shorten the life of this product. The effect of electromagnetic interference must be reduced by

using a noise filter or by other means. Otherwise nearby electronic equipment may be affected. Appropriate measures must be taken to suppress harmonics.

Otherwise power supply harmonics from the inverter may heat/ damage the power factor correction capacitor and generator. When driving a 600V class motor by the inverter, the motor must

be an insulation-enhanced motor or measures must be taken to suppress surge voltage. Surge voltage attributable to the wiring constants may occur at the motor terminals, deteriorating the insulation of the motor. When parameter clear or all parameter clear is performed, the

required parameters must be set again before starting operations because all parameters return to their initial values. The inverter can be easily set for high-speed operation. Before

changing its setting, the performances of the motor and machine must be fully examined. Stop status cannot be hold by the inverter's brake function. In

addition to the inverters brake function, a holding device must be installed to ensure safety. Before running an inverter which had been stored for a long

period, inspection and test operation must be performed. Static electricity in your body must be discharged before you

touch the product. Only one PM motor can be connected to an inverter. A PM motor must be used under PM motor control. Do not use a

synchronous motor, induction motor, or synchronous induction motor. Do not connect a PM motor in the induction motor control

settings (initial settings). Do not use an induction motor in the PM motor control settings. It will cause a failure. In the system with a PM motor, the inverter power must be

turned ON before closing the contacts of the contactor at the output side.

Emergency stop A safety backup such as an emergency brake must be provided

for devices or equipment in a system to prevent hazardous conditions in case of failure of this product or an external device controlling this product. When the breaker on the inverter input side trips, the wiring must

be checked for fault (short circuit), and internal parts of the inverter for a damage, etc. The cause of the trip must be identified and removed before turning ON the power of the breaker. When a protective function activates, take an appropriate

corrective action, then reset the inverter, and resume the operation.

Maintenance, inspection and parts replacement Do not carry out a megger (insulation resistance) test on the

control circuit of the inverter. It will cause a failure. Disposal The inverter must be treated as industrial waste.

(b) Converter unit (FR-CC2-C)

(c) Three-phase AC power supply Must be within the permissible power supply specifications of the converter unit.

76

(d) Molded case circuit breaker (MCCB), earth leakage circuit breaker (ELB), or fuse

Must be selected carefully since an inrush current flows in the converter unit at power ON.

14

(e) Magnetic contactor (MC) Install this to ensure safety. Do not use this to start and stop the inverter. Doing so will shorten the life of the inverter and the converter unit.

52

(f) AC reactor

Install this to suppress harmonics and to improve the power factor. An AC reactor is required when installing the inverter near a large power supply system (1000 kVA or more). Under such condition, the inverter and the converter unit may be damaged if you do not use a reactor. Select a reactor according to the applied motor capacity.

51

(g) Noise filter Suppresses the noise radiated from the power supply side of the converter unit.

49

(h) USB connection

Connect between the inverter and a personal computer with a USB (ver. 1.1) cable. Use a USB memory device to copy parameter settings or use the trace function.

45

(i) Noise filter Install this to reduce the electromagnetic noise generated from the inverter and the converter unit. The noise filter is effective in the range from about 0.5 to 5 MHz.

49

(j) Induction motor Connect a squirrel-cage induction motor.

(k) Contactor Example) No-fuse switch (DSN type)

Connect this for an application where a PM motor is driven by the load even while the inverter power is OFF. Do not open or close the contactor while the inverter is running (outputting).

(l) PM motor A PM motor can be used. A PM motor cannot be driven by the commercial power supply.

2.3 Installation of the inverter and enclosure design When designing or manufacturing an inverter enclosure, determine the structure, size, and device layout of the enclosure by

fully considering the conditions such as heat generation of the contained devices and the operating environment. An inverter

uses many semiconductor devices. To ensure higher reliability and long period of operation, operate the inverter in the

ambient environment that completely satisfies the equipment specifications.

2.3.1 Inverter installation environment The following table lists the standard specifications of the inverter installation environment. Using the inverter in an

environment that does not satisfy the conditions deteriorates the performance, shortens the life, and causes a failure. Refer to

the following points, and take adequate measures.

Standard environmental specifications of the inverter

Temperature applicable for a short time, for example, in transit.

For the installation at an altitude above 1000 m, consider a 3% reduction in the rated current per 500 m increase in altitude.

Surrounding Air Temperature is a temperature measured at a measurement position in an enclosure.

Ambient Temperature is a temperature outside an enclosure.

Temperature The permissible surrounding air temperature of the inverter is between -10C and +40C (-10C and +50C at the LD ratings).

Always operate the inverter within this temperature range. Operation outside this range will considerably shorten the service

lives of the semiconductors, parts, capacitors and others. Take the following measures to keep the surrounding air

temperature of the inverter within the specified range.

(a) Measures against high temperature

Use a forced ventilation system or similar cooling system. (Refer to page 20.)

Install the enclosure in an air-conditioned electric chamber.

Block direct sunlight.

Provide a shield or similar plate to avoid direct exposure to the radiated heat and wind of a heat source.

Ventilate the area around the enclosure well.

(b) Measures against low temperature

Provide a space heater in the enclosure.

Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)

(c) Sudden temperature changes

Select an installation place where temperature does not change suddenly.

Avoid installing the inverter near the air outlet of an air conditioner.

If temperature changes are caused by opening/closing of a door, install the inverter away from the door.

NOTE For the amount of heat generated by the inverter unit, refer to page 19.

INSTALLATION AND WIRING 17

Installation of the inverter and enclosure design

Humidity Operate the inverter within the ambient air humidity of usually 45 to 95%. Too high humidity will pose problems of reduced

insulation and metal corrosion. On the other hand, too low humidity may cause a spatial electrical breakdown. The humidity

conditions for the insulation distance defined in JEM 1103 standard "Insulation Distance from Control Equipment" is 45 to

85%.

(a) Measures against high humidity

Make the enclosure enclosed, and provide it with a hygroscopic agent.

Provide dry air into the enclosure from outside.

Provide a space heater in the enclosure.

(b) Measures against low humidity

Air with proper humidity can be blown into the enclosure from outside. Also when installing or inspecting the unit, discharge

your body (static electricity) beforehand, and keep your body away from the parts and patterns.

(c) Measures against condensation

Condensation may occur if frequent operation stops change the in-enclosure temperature suddenly or if the outside air

temperature changes suddenly.

Condensation causes such faults as reduced insulation and corrosion.

Take the measures against high humidity in (a).

Do not power OFF the inverter. (Keep the start signal of the inverter OFF.)

Dust, dirt, oil mist Dust and dirt will cause such faults as poor contacts, reduced insulation and cooling effect due to the moisture-absorbed

accumulated dust and dirt, and in-enclosure temperature rise due to a clogged filter. In an atmosphere where conductive

powder floats, dust and dirt will cause such faults as malfunction, deteriorated insulation and short circuit in a short time.

Since oil mist will cause similar conditions, it is necessary to take adequate measures.

Precautions

Place the inverter in a totally enclosed enclosure.

Take measures if the in-enclosure temperature rises. (Refer to page 20.)

Purge air.

Pump clean air from outside to make the in-enclosure air pressure higher than the outside air pressure.

Corrosive gas, salt damage If the inverter is exposed to corrosive gas or to salt near a beach, the printed board patterns and parts will corrode or the

relays and switches will result in poor contact.

In such places, take the measures given above.

Explosive, flammable gases As the inverter is non-explosion proof, it must be contained in an explosion-proof enclosure. In places where explosion may

be caused by explosive gas, dust or dirt, an enclosure cannot be used unless it structurally complies with the guidelines and

has passed the specified tests. This makes the enclosure itself expensive (including the test charges). The best way is to

avoid installation in such places and install the inverter in a non-hazardous place.

High altitude Use the inverter at an altitude of within 2500 m. For use at an altitude above 1000 m, consider a 3% reduction in the rated

current per 500 m increase in altitude.

If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure will deteriorate dielectric

strength.

18 INSTALLATION AND WIRING

Installation of the inverter and enclosure design

Vibration, impact The vibration resistance of the inverter is up to 2.9 m/s2 at 10 to 55 Hz frequency and 1 mm amplitude for the directions of X,

Y, Z axes. Applying vibration and impacts for a long time may loosen the structures and cause poor contacts of connectors,

even if those vibration and impacts are within the specified values.

Especially when impacts are applied repeatedly, caution must be taken because such impacts may break the installation feet.

Precautions

Provide the enclosure with rubber vibration isolators.

Strengthen the structure to prevent the enclosure from resonance.

Install the enclosure away from the sources of the vibration.

2.3.2 Amount of heat generated by the inverter Regarding the amount of heat generated in the FR-F860 series inverter The amount of heat generated by the inverter unit and converter unit is shown in the following tables.

2.3.3 Cooling system types for inverter enclosure From the enclosure that contains the inverter, the heat of the inverter and other equipment (transformers, lamps, resistors,

etc.) and the incoming heat such as direct sunlight must be dissipated to keep the in-enclosure temperature lower than the

permissible temperatures of the in-enclosure equipment including the inverter.

The cooling systems are classified as follows in terms of the cooling calculation method.

(a) Cooling by natural heat dissipation from the enclosure surface (totally enclosed type)

(b) Cooling by heat sink (aluminum fin, etc.)

(c) Cooling by ventilation (forced ventilation type, pipe ventilation type)

(d) Cooling by heat exchanger or cooler (heat pipe, cooler, etc.)

Cooling system Enclosure structure Comment

Natural

Natural ventilation (enclosed type / open type)

This system is low in cost and generally used, but the enclosure size increases as the inverter capacity increases. This system is for relatively small capacities.

Natural ventilation (totally enclosed type)

Being a totally enclosed type, this system is the most appropriate for hostile environment having dust, dirt, oil mist, etc. The enclosure size increases depending on the inverter capacity.

Forced air

Heat sink cooling This system has restrictions on the heat sink mounting position and area. This system is for relatively small capacities.

Forced ventilation This system is for general indoor installation. This is appropriate for enclosure downsizing and cost reduction, and often used.

Heat pipe This is a totally enclosed for enclosure downsizing.

2.3.4 Inverter installation Inverter placement

Install the inverter on a strong surface securely with screws.

Leave enough clearances and take cooling measures.

Avoid places where the inverter is subjected to direct sunlight, high temperature and high humidity.

Install the inverter on a nonflammable wall surface.

When encasing multiple inverters in an enclosure, install them in parallel as a cooling measure.

For heat dissipation and maintenance, keep clearance between the inverter and the other devices or enclosure surface.

The clearance below the inverter is required as a wiring space, and the clearance above the inverter is required as a heat

dissipation space.

When designing or building an enclosure for the inverter, carefully consider influencing factors such as heat generation of

the contained devices and the operating environment.

For replacing the cooling fan, 30 cm or more of space is necessary in front of the inverter. Refer to page 68 for fan replacement.

Installation orientation of the inverter Install the inverter on a wall as specified. Do not mount it horizontally or in any other way.

Above the inverter Heat is blown up from inside the inverter by the small fan built in the unit. Any equipment placed above the inverter should be

heat resistant.

Arrangement of the ventilation fan and inverter

When multiple inverters and converter units are placed in the

same enclosure, generally arrange them horizontally as shown

in the figure on the right.

Do not place multiple products vertically. The exhaust air

temperature of the inverter and the converter unit may be

increased.

When mounting multiple inverters and converter units, fully take

caution not to make the surrounding air temperature of the

inverter and the converter unit higher than the permissible value

by providing ventilation and increasing the enclosure size. Arrangement of multiple inverters and converter units

Heat generated in the inverter is blown up from the bottom of

the unit as warm air by the cooling fan. When installing a

ventilation fan for that heat, determine the place of ventilation

fan installation after fully considering an air flow. (Air passes

through areas of low resistance. Make an airway and airflow

plates to expose the inverter to cool air.)

Terminal connection diagrams

A jumper is installed across terminal R1/L11 and terminal P/+, and across terminal S1/L21 and terminal N/-. When using a separate power

supply for the control circuit, remove the jumpers.

The function of these terminals can be changed with the input terminal assignment (Pr.178 to Pr.189). Terminal JOG is also used as the pulse train input terminal. Use Pr.291 to choose JOG or pulse.

The X10 signal (NC contact input specification) is assigned to the terminal MRS in the initial setting. Set Pr.599 = "0" to change the input

specification of the X10 signal to NO contact.

No function is assigned in the initial setting. Use Pr.186 for function assignment.

Terminal input specifications can be changed by analog input specification switchover (Pr.73, Pr.267). To input a voltage (0 to 5 V/0 to 10 V), set

the voltage/current input switch OFF. To input a current (4 to 20 mA), set the voltage/current input switch ON. Terminals 10 and 2 are also used

as a PTC input terminal (Pr.561). It is recommended to use 2 W 1 k when the frequency setting signal is changed frequently.

The function of these terminals can be changed with the output terminal assignment (Pr.195, Pr.196). The function of these terminals can be changed with the output terminal assignment (Pr.190 to Pr.194). No function is assigned in the initial setting. Use Pr.192 for function assignment.

NOTE To prevent a malfunction due to noise, keep the signal cables 10 cm or more away from the power cables. Also, keep the

cables of the main circuit for input and output separated.

After wiring, wire offcuts must not be left in the inverter.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter clean.

When drilling mounting holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the

inverter.

Set the voltage/current input switch correctly. Incorrect setting may cause a fault, failure or malfunction.

Terminals S1, S2, SIC, So (SO), and SOC are for manufacturer setting. Do not remove the shorting wires across terminals S1

and PC, terminals S2 and PC, and terminals SIC and SD. When the shorting wires are removed, the inverter does not

operate.

Connection between the converter unit and the inverter Perform wiring so that the commands sent from the converter unit are transmitted to the inverter without fail. Incorrect

connection may damage the converter unit and the inverter.

For the wiring length, refer to the table below.

For the cable gauge of the cable across the main circuit terminals P/+ and N/- (P and P, N and N), refer to page 29.

Do not install an MCCB across terminals P/+ and N/- (across terminals P and P/+ or across N and N/-). Connecting the opposite polarity of

terminals N/- and P/+ will damage the inverter.

For the terminal used for the X10 signal input, set "10" in any of Pr.178 to Pr.189 (Input terminal function selection) to assign the function.

(The X10 signal is assigned to terminal MRS in the initial setting.)

For the X10 signal, NC contact input specification is selected in the initial setting. Set Pr.599 = "0" to change the input specification to NO

contact.

For the terminal used for the X11 signal input, set "11" in any of Pr.178 to Pr.189 (Input terminal function selection) to assign the function. For

RS-485 or any other communication where the start command is only transmitted once, use the X11 signal to save the operation mode at the

time of an instantaneous power failure.

Always connect terminal RDA of the converter unit and terminal MRS (X10) of the inverter, and terminal SE of the converter unit and terminal SD

(sink logic) of the inverter. Not connecting these terminals may damage the converter unit.

Main circuit terminals

The line voltage drop can be calculated by the following formula:

Line voltage drop [V]=

Use a larger diameter cable when the wiring distance is long or when it is desired to decrease the voltage drop (torque

reduction) in the low speed range.

NOTE Tighten the terminal screw to the specified torque.

A screw that has been tightened too loosely can cause a short circuit or malfunction.

A screw that has been tightened too tightly can cause a short circuit or malfunction due to the unit breakage.

Use crimp terminals with insulation sleeves to wire the power supply and motor.

Total wiring length With induction motor Connect one or more general-purpose motors within the total wiring length 500 m.

With PM motor Use the wiring length of 100 m or shorter when connecting a PM motor.

Use one PM motor for one inverter. Multiple PM motors cannot be connected to an inverter.

NOTE Especially for long-distance wiring, the inverter may be affected by a charging current caused by the stray capacitances of the

wiring, leading to a malfunction of the overcurrent protective function or fast response current limit function or a malfunction or

fault of the equipment connected on the inverter output side. If the fast-response current limit function malfunctions, disable

this function. (For the details of Pr.156 Stall prevention operation selection, refer to the Instruction Manual (Detailed) of the

2.5.5 Earthing (grounding) precautions Always earth (ground) the motor, the inverter, and the converter unit.

Purpose of earthing (grounding) Generally, an electrical apparatus has an earth (ground) terminal, which must be connected to the ground before use.

An electrical circuit is usually insulated by an insulating material and encased. However, it is impossible to manufacture an

insulating material that can shut off a leakage current completely, and actually, a slight current flows into the case. The

purpose of earthing (grounding) the case of an electrical apparatus is to prevent operators from getting an electric shock from

this leakage current when touching it.

To avoid the influence of external noises, the earthing (grounding) is important to EMI-sensitive equipment that handle low-

level signals or operate very fast such as audio equipment, sensors, computers.

Earthing (grounding) system to be established As described previously, the purpose of earthing (grounding) is roughly classified into the electrical shock prevention and the

prevention of malfunction due to the influence of electromagnetic noise. These two purposes should be clearly distinguished,

and the appropriate earth (ground) system must be established to prevent the leakage current having the inverter's high

frequency components from reversing through another earth (ground) point for malfunction prevention by following these

instructions.

Make the separate earth (ground) connection (I) for high frequency products such as the inverter from any other devices

(EMI-sensitive devices described above) wherever possible.

Establishing adequate common (single-point) earth (ground) system (II) shown in the following figure is allowed only in

cases where the separate earth (ground) system (I) is not feasible. Do not make inadequate common (single-point) earth

(ground) connection (III).

As leakage currents containing many high frequency components flows into the earthing (grounding) cables of the inverter

and peripheral devices the inverter must also be earthed (grounded) separately from the EMI-sensitive devices described

above.

In a high building, it may be effective to use its iron structure frames as earthing (grounding) electrode for EMI prevention in

order to separate from the earth (ground) system for electric shock prevention.

Earthing (Grounding) must conform to the requirements of national and local safety regulations and electrical codes

(NEC section 250, IEC 61140 class 1 and other applicable standards).

A neutral-point earthed (grounded) power supply in compliance with EN standard must be used.

Use the thickest possible earthing (grounding) cable. The earthing (grounding) cable should be equal to the size

indicated in the table on page 29.

The earthing (grounding) point should be as close as possible to the inverter, and the earth (ground) cable length should

be as short as possible.

Run the earthing (grounding) cable as far away as possible from the I/O wiring of the EMI-sensitive devices and run

them in parallel in the minimum distance.

Wiring method Wire insertion

Use crimp terminals and stripped wire for the control circuit wiring. For single wire, the stripped wire can be used without crimp

terminal.

Connect the end of wires (crimp terminal or stranded wire) to the terminal block.

(1) Strip the signal wires as shown below. If too much of the wire is stripped, a short circuit may occur with neighboring wires.

If not enough of the wire is stripped, wires may become loose and fall out.

Twist the stripped end of wires to prevent them from fraying. Do not solder it.

(2) Use appropriate crimp terminals (ferrules, blade terminals, etc.).

Insert wires to the crimp terminal, and check that the wires come out for about 0 to 0.5 mm from a sleeve.

Check the condition of the crimp terminals after crimping. Do not use the crimp terminals of which the crimping is

inappropriate, or the face is damaged.

Control circuit

Signal inputs by contactless switches The contact input terminals of the inverter (STF, STR, STP (STOP), RH, RM, RL, JOG, RT, MRS, RES, AU, CS) can be

controlled using a transistor instead of a contact switch as shown below.

2.6.5 Wiring precautions It is recommended to use a cable of 0.75 mm2 for the connection to the control circuit terminals.

The wiring length should be 30 m at the maximum.

Use two or more parallel micro-signal contacts or twin contacts to prevent

contact faults when using contact inputs since the control circuit input signals

are micro-currents.

To suppress EMI, use shielded or twisted cables for the control circuit

terminals and run them away from the main and power circuits (including the

200V relay sequence circuit). For the cables connected to the control circuit terminals, connect their shields to the common

terminal of the connected control circuit terminal. When connecting an external power supply to the terminal PC, however,

connect the shield of the power supply cable to the negative side of the external power supply. Do not directly earth

(ground) the shield to the enclosure, etc.

Always apply a voltage to the fault output terminals (A1, B1, C1, A2, B2, C2) via a relay coil, lamp, etc.

Separate the wiring of the control circuit away from the wiring of the main circuit.

Make cuts in rubber bush of the inverter side and lead the wires through.

2.6.6 When using separate power supplies for the control circuit and the main circuit

Cable size for the control circuit power supply (terminals R1/L11 and S1/ L21)

Terminal screw size: M4

Cable gauge: 0.75 mm2 to 2 mm2

Tightening torque: 1.5 Nm

Connection method When a fault occurs, opening of the electromagnetic contactor (MC) on the inverter power supply side results in power loss in

the control circuit, disabling the fault output signal retention. Terminals R1/L11 and S1/L21 are provided to hold a fault signal.

In this case, connect the power supply terminals R1/L11 and S1/L21 of the control circuit to the input side of the MC.

The terminals R1/L11 and S1/L21 are connected to the terminals P/+ and N/- with a jumper respectively. Do not connect the

power cable to incorrect terminals. Doing so may damage the inverter.

(a) Remove the upper screws. (b) Remove the lower screws. (c) Pull the jumper toward you to remove. (d) Connect the separate power supply cable for the control circuit to the upper terminals (R1/L11, S1/L21).

NOTE When using separate power supplies, always remove the jumpers from terminals R1/L11 and S1/L21. The inverter may be

damaged if the jumpers are not removed.

The voltage should be the same as that of the main control circuit when the control circuit power is supplied from other than

the input side of the MC.

When using a separate power supply from R1/L11 and S1/L21, the necessary power capacity of the separate power supply is

80 VA.

If the main circuit power is switched OFF (for 0.1 s or more) then ON again, the inverter is reset and a fault output will not be

held.

2.6.7 When supplying 24 V external power to the control circuit

Connect a 24 V external power supply across terminals +24 and SD. Connecting a 24 V external power supply enables I/O terminal ON/OFF operation, operation panel displays, control functions, and communication during communication operation even during power-OFF of inverter's main circuit power supply. When the main circuit power supply is turned ON, the power supply changes from the 24 V external power supply to the main circuit power supply.

Specification of the applied 24 V external power supply

Commercially available products (as of February 2015)

Starting and stopping the 24 V external power supply operation Supplying 24 V external power while the main circuit power is OFF starts the 24 V external power supply operation.

Likewise, turning OFF the main circuit power while supplying 24 V external power starts the 24 V external power supply

operation.

Turning ON the main circuit power stops the 24 V external power supply operation and enables the normal operation.

NOTE When the 24 V external power is supplied while the main circuit power supply is OFF, the inverter operation is disabled.

In the initial setting, when the main power supply is turned ON during the 24 V external power supply operation, a reset is

performed in the inverter, then the power supply changes to the main circuit power supply. (The reset can be disabled using

Pr.30.)

Confirming the 24 V external power supply input During the 24 V external power supply operation, the alarm lamp blinks.

During the 24 V external power supply operation, the 24 V external power supply operation signal (EV) is output. To use the

EV signal, set "68 (positive logic) or 168 (negative logic)" in one of Pr.190 to Pr.196 (Output terminal function selection) to assign function to an output terminal.

Operation while the 24 V external power is supplied Fault records and parameters can be read and parameters can be written (when the parameter write from the operation

panel is enabled) using the operation panel keys.

The safety stop function is disabled during the 24 V external power supply operation.

During the 24 V external power supply operation, monitored items related to inputs to main circuit power supply, such as

output current and converter output voltage, are invalid.

The alarms, which have occurred when the main circuit power supply is ON, continue to be output after the power supply is

changed to the 24 V external power supply. Perform the inverter reset or turn OFF then ON the power to reset the faults.

The output data is retained when "1 or 11" is set in Pr.495 Remote output selection.

NOTE Inrush current equal to or higher than the 24 V external power supply specification may flow at power-ON. Confirm that the

power supply and other devices are not affected by the inrush current and the voltage drop caused by it. Depending on the

power supply, the inrush current protection may be activated to disable the power supply. Select the power supply and

capacity carefully.

When the wiring length between the external power supply and the inverter is long, the voltage often drops. Select the

appropriate wiring size and length to keep the voltage in the rated input voltage range.

In a serial connection of several inverters, the current increases when it flows through the inverter wiring near the power

supply. The increase of the current causes voltage to drop further. Use the inverter after confirming that the input voltage of

each converter unit is within the rated input voltage range. Depending on the power supply, the inrush current protection may

be activated to disable the power supply. Select the power supply and capacity carefully.

"E.SAF" or "E.P24" may appear when the start-up time of the 24 V power supply is too long (less than 1.5 V/s) in the 24 V

external power supply operation.

"E.P24" may appear when the 24 V external power supply input voltage is low. Check the external power supply input.

Do not touch the control circuit terminal block (circuit board) during the 24 V power supply operation (when conducted).

Otherwise you may get an electric shock or burn.

Electro-magnetic interference (EMI) and leakage currents

3.1 Electro-magnetic interference (EMI) and leakage currents

3.1.1 Leakage currents and precautions Capacitances exist between the inverter I/O cables, other cables and earth and in the motor, through which a leakage current

flows. Since its value depends on the static capacitances, carrier frequency, etc., low acoustic noise operation at the

increased carrier frequency of the inverter will increase the leakage current. Therefore, take the following precautions. Select

the earth leakage current breaker according to its rated sensitivity current, independently of the carrier frequency setting.

To-earth (ground) leakage currents Leakage currents may flow not only into the inverter's own line but also into the other lines through the earthing (grounding)

cable, etc. These leakage currents may operate earth leakage circuit breakers and earth leakage relays unnecessarily.

Precautions

If the carrier frequency setting is high, decrease the Pr.72 PWM frequency selection setting.

Note that motor noise increases. Selecting Pr.240 Soft-PWM operation selection makes the sound inoffensive.

By using earth leakage circuit breakers designed for harmonic and surge suppression in the inverter's own line and other

line, operation can be performed with the carrier frequency kept high (with low noise).

To-earth (ground) leakage currents

Take caution as long wiring will increase the leakage current. Decreasing the carrier frequency of the inverter reduces the

leakage current.

Increasing the motor capacity increases the leakage current.

Line-to-line leakage currents Harmonics of leakage currents flowing in static capacitances between the inverter output cables may operate the external

thermal relay unnecessarily.

Precautions

Use Pr.9 Electronic thermal O/L relay.

If the carrier frequency setting is high, decrease the Pr.72 PWM frequency selection setting.

Note that motor noise increases. Selecting Pr.240 Soft-PWM operation selection makes the sound inoffensive.

To ensure that the motor is protected against line-to-line leakage currents, it is recommended to use a temperature sensor

to directly detect motor temperature.

Installation and selection of the molded case circuit breaker

Install a molded case circuit breaker (MCCB) on the power receiving side to protect the wiring at the inverter input side.

Select an MCCB according to the inverter input side power factor, which depends on the power supply voltage, output

frequency and load. Especially for a completely electromagnetic MCCB, a slightly large capacity must be selected since its

operation characteristic varies with harmonic currents. (Check it in the data of the corresponding breaker.)

Electro-magnetic interference (EMI) and leakage currents

3.1.2 Precautions against inverter-generated EMI Some electromagnetic noises enter the inverter or the converter unit to cause its malfunction, and others are radiated by the

inverter or the converter unit to cause the peripheral devices to malfunction. Though the inverter or the converter unit is

designed to have high immunity performance, it handles low-level signals, so it requires the following basic techniques. Also,

since the inverter chops outputs at high carrier frequency, that could generate electromagnetic noises. To prevent peripheral

devices from malfunctioning due to electromagnetic noise, take precautions to suppress EMI. These techniques differ slightly

depending on EMI paths.

Basic techniques

- Do not run the power cables (I/O cables) and signal cables of the inverter or the converter unit in parallel with each other

and do not bundle them.

- Use shielded twisted pair cables for the detector connecting and control signal cables and connect the sheathes of the

shielded cables to terminal SD.

- Ground (Earth) the inverter or the converter unit, motor, etc. at one point.

Techniques to reduce electromagnetic noises that enter and cause a malfunction of the inverter or the converter unit (EMI

precautions)

When devices that generate many electromagnetic noises (which use magnetic contactors, electromagnetic brakes, many

relays, for example) are installed near the inverter or the converter unit and it may malfunction due to electromagnetic

noises, the following precautions must be taken:

- Provide surge suppressors for devices that generate many electromagnetic noises to suppress electromagnetic noises.

- Install data line filters (page 50) to signal cables.

- Ground (Earth) the shields of the detector connection and control signal cables with cable clamp metal.

Techniques to reduce electromagnetic noises that are radiated by the inverter or converter unit to cause the peripheral

devices to malfunction (EMI precautions)

Noises generated from the inverter or the converter unit are largely classified into those radiated by the cables connected to

the inverter or the converter unit and its main circuits (I/O), those electromagnetically and electrostatically induced to the

signal cables of the peripheral devices close to the main circuit power supply, and those transmitted through the power

supply cables.

Electro-magnetic interference (EMI) and leakage currents

Data line filter Data line filter is effective as an EMI precaution. Provide a data line filter for the detector cable, etc.

EMI precautions example

Noise propagation path Precautions

(a)(b)(c)

When devices that handle low-level signals and are liable to malfunction due to electromagnetic noises, e.g. instruments, receivers and sensors, are contained in the enclosure that contains the inverter or the converter unit, or when their signal cables are run near the inverter, the devices may malfunction due to by air-propagated electromagnetic noises. The following precautions must be taken: Install easily affected devices as far away as possible from the inverter or the converter unit. Run easily affected signal cables as far away as possible from the inverter or the converter unit, and its I/O cables.

Do not run the signal cables and power cables (inverter or converter unit I/O cables) in parallel with each other and do not bundle them.

Inserting a line noise filter into the output suppresses the radiated noise from the cables. Use shielded cables as signal cables and power cables and run them in individual metal conduits to produce further effects.

(d)(e)(f)

When the signal cables are run in parallel with or bundled with the power cables, magnetic and static induction noises may be propagated to the signal cables to cause malfunction of the devices and the following precautions must be taken: Install easily affected devices as far away as possible from the inverter or the converter unit. Run easily affected signal cables as far away as possible from the inverter or the converter unit, and its I/O cables.

Do not run the signal cables and power cables (inverter or converter unit I/O cables) in parallel with each other and do not bundle them.

Use shielded cables as signal cables and power cables and run them in individual metal conduits to produce further effects.

(g)

When the power supplies of the peripheral devices are connected to the power supply of the inverter or the converter unit in the same line, its generated noises may flow back through the power supply cables to cause malfunction of the devices and the following precautions must be taken: Install the line noise filter to the power cables (output cables) of the inverter.

(h)

When a closed loop circuit is formed by connecting the peripheral device wiring to the inverter or the converter unit, leakage currents may flow through the earthing (grounding) cable of the inverter or the converter unit to cause the device to malfunction. In that case, disconnecting the earthing (grounding) cable from the device may stop the malfunction of the device.

Power supply harmonics

3

3.2 Power supply harmonics

3.2.1 Power supply harmonics The inverter may generate power supply harmonics from its converter circuit to affect the power generator, power factor

correction capacitor etc. Power supply harmonics are different from noise and leakage currents in source, frequency band and

transmission path. Take the following precaution suppression techniques.

The differences between harmonics and noises

Precautions

NOTE The power factor improving capacitor and surge suppressor on the inverter output side may be overheated or damaged by

the harmonic components of the inverter output. Also, since an excessive current flows in the inverter to activate overcurrent

protection, do not provide a capacitor and surge suppressor on the inverter output side when the motor is driven by the

inverter. For power factor improvement, install a reactor on the inverter input side or in the DC circuit.

3.3 Installation of a reactor When the inverter is connected near a large-capacity power transformer (1000 kVA or more) or when a power factor

correction capacitor is to be switched over, an excessive peak current may flow in the power input circuit, damaging the

converter circuit. To prevent this, always install an AC reactor.

Item Harmonics Noise

Frequency Normally 40th to 50th degrees or less (3 kHz or less).

High frequency (several 10 kHz to 1 GHz order).

Environment To-electric channel, power impedance. To-space, distance, wiring path,

Quantitative understanding Theoretical calculation possible. Random occurrence, quantitative grasping difficult.

Generated amount Nearly proportional to the load capacity. Changes with the current variation ratio. (Gets larger as switching speed increases.)

Affected equipment immunity Specified by standards per equipment. Different depending on maker's equipment specifications.

Precaution Provide a reactor. Increase distance.

The harmonic current generated from the inverter

to the input side differs according to various

conditions such as the wiring impedance,

whether a reactor is used or not, and output

frequency and output current on the load side.

For the output frequency and output current, we

understand that this should be calculated in the

conditions under the rated load at the maximum

operating frequency.

PRECAUTIONS FOR USE OF THE INVERTER 51

Power-OFF and magnetic contactor (MC)

3.4 Power-OFF and magnetic contactor (MC)

Converter unit input side magnetic contactor (MC) On the converter unit input side, it is recommended to provide an MC for the following purposes:

(Refer to page 14 for selection.)

To disconnect the inverter from the power supply at activation of a protective function or at malfunctioning of the driving

system (emergency stop, etc.).

To prevent any accident due to an automatic restart at power restoration after an inverter stop made by a power failure.

To separate the inverter from the power supply to ensure safe maintenance and inspection work.

If using an MC for emergency stop during operation, select an MC regarding the converter unit input side current as JEM

1038-AC-3 class rated current.

NOTE Since repeated inrush currents at power ON will shorten the life of the converter circuit (switching life is about 1,000,000

times), frequent starts and stops of the magnetic contactor must be avoided. Turn ON/OFF the inverter start controlling

terminals (STF, STR) to run/stop the inverter.

Inverter start/stop circuit example

As shown below, always use the start signal (ON or OFF of STF(STR) signal) to make a start or stop.

Install a stepdown transformer.

Connect the power supply terminals R1/L11, S1/L21 of the control circuit to the input side of the MC to hold an alarm signal when the inverter's

protective circuit is activated. At this time, remove jumpers across terminals R1/L11 and S1/L21. (Refer to page 41 for removal of the jumper.)

Handling of the magnetic contactor on the inverter's output side Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop. When the

magnetic contactor is turned ON while the inverter is operating, overcurrent protection of the inverter and such will activate.

When an MC is provided to switch to a commercial power supply, for example, it is recommended to use the electronic bypass

function Pr.135 to Pr.139. (The commercial power supply operation is not available with PM motors.)

Handling of the manual contactor on the inverter's output side A PM motor is a synchronous motor with high-performance magnets embedded inside. High-voltage is generated at the motor

terminals while the motor is running even after the inverter power is turned OFF. In an application where the PM motor is

driven by the load even after the inverter is powered OFF, a low-voltage manual contactor must be connected at the inverter's

output side.

Precautions against deterioration of the 600 V class motor insulation

3

NOTE Before wiring or inspection for a PM motor, confirm that the PM motor is stopped. In an application, such as fan and blower,

where the motor is driven by the load, a low-voltage manual contactor must be connected at the inverter's output side, and

wiring and inspection must be performed while the contactor is open. Otherwise you may get an electric shock.

Do not open or close the contactor while the inverter is running (outputting).

3.5 Precautions against deterioration of the 600 V class motor insulation

In the PWM type inverter, a surge voltage attributable to wiring constants is generated at the motor terminals. Especially for a 600V class motor, the surge voltage may deteriorate the insulation.

Surge voltage at a motor terminal by motor wiring length (reference)

When the 600V class motor is driven by the inverter, consider the following measures:

Measures Inverter duty motor

Select an inverter duty motor. Many motor manufacturers sell motors with insulation systems designed to withstand the

stress imposed by PWM inverters

AC reactor

For added protection, install an AC reactor on the inverter output

PRECAUTIONS FOR USE OF THE INVERTER 53

Checklist before starting operation

3.6 Checklist before starting operation The FR-F860 series inverter and FR-CC2-C converter unit are highly reliable products, but incorrect peripheral circuit making

or operation/handling method may shorten the product life or damage the products.

Before starting operation, always recheck the following points.

Point to be checked Action Refer

to page

Check by user

Crimp terminals are insulated. Use crimp terminals with insulation sleeves to wire the power supply and the motor.

-

The wiring between the power supply (R/L1, S/L2, T/L3) and the motor (U, V, W) is correct.

Application of power to the output terminals (U, V, W) of the inverter will damage the inverter. Never perform such wiring.

28

No wire offcuts are left from the time of wiring.

Wire offcuts can cause an alarm, failure or malfunction. Always keep the inverter and the converter unit clean. When drilling mounting holes in an enclosure etc., take caution not to allow chips and other foreign matter to enter the inverter and the converter unit.

-

The main circuit cable gauge is correctly selected.

Use an appropriate cable gauge to suppress the voltage drop to 2% or less. If the wiring distance is long between the inverter and motor, the voltage drop in the main circuit will cause the motor torque to decrease especially during the output of a low frequency.

29

The total wiring length is within the specified length.

Keep the total wiring length is within the specified length. In long distance wiring, charging currents due to stray capacitance in the wiring may degrade the fast-response current limit operation or cause the equipment on the inverter's output side to malfunction. Pay attention to the total wiring length.

29

Precautions are taken against EMI.

The input/output (main circuit) of the inverter and the converter unit includes high frequency components, which may interfere with the communication devices (such as AM radios) used near the inverter and the converter unit. In such case, enable the built-in EMC filter of the converter unit (connect two of the EMC filter ON/OFF female connectors to the ON male connectors) to minimize interference.

49

Countermeasures are taken against electrical corrosion on the motor bearing.

When a motor is driven by the inverter, axial voltage is generated on the motor shaft, which may cause electrical corrosion of the bearing in rare cases depending on the wiring, load, operating conditions of the motor or a specific inverter setting (high carrier frequency). Contact your sales representative to take appropriate countermeasures for the motor. The following shows examples of countermeasures for the inverter. Decrease the carrier frequency. Provide a common mode choke on the output side of the inverter.

Recommended common mode choke: FT-3KM F series FINEMET

common mode choke cores manufactured by Hitachi Metals, Ltd.

FINEMET is a registered trademark of Hitachi Metals, Ltd.

-

On the inverter's output side, there is no power factor correction capacitor, surge suppressor, or radio noise filter installed.

Doing so will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above devices is connected, immediately remove it.

-

When performing an inspection or rewiring on the product that has been energized, the operator has waited long enough after shutting off the power supply.

For a short time after the power-OFF, a high voltage remains in the smoothing capacitor, and it is dangerous. Before performing an inspection or rewiring, wait 10 minutes or longer after the power supply turns OFF, then confirm that the voltage across the main circuit terminals P/+ and N/- of the inverter is low enough using a tester, etc.

-

The inverter's output side has no short circuit or ground fault occurring.

A short circuit or earth (ground) fault on the inverter's output side may damage the inverter module.

Fully check the insulation resistance of the circuit prior to inverter operation since repeated short circuits caused by peripheral circuit inadequacy or an earth (ground) fault caused by wiring inadequacy or reduced motor insulation resistance may damage the inverter module.

Fully check the to-earth (ground) insulation and phase-to-phase insulation of the inverter's output side before power-ON. Especially for an old motor or use in hostile atmosphere, securely check the motor insulation resistance, etc.

-

The circuit is not configured to use the converter unit's input-side magnetic contactor to start/stop the inverter frequently.

Since repeated inrush currents at power ON will shorten the life of the inverter and the converter unit, frequent starts and stops of the magnetic contactor must be avoided. Turn ON/OFF the inverter's start signals (STF, STR) to run/ stop the inverter.

52

54 PRECAUTIONS FOR USE OF THE INVERTER

Checklist before starting operation

3

The voltage applied to the I/O signal circuits of the inverter and the converter unit is within the specifications.

Application of a voltage higher than the permissible voltage to the I/O signal circuits of the inverter and the converter unit or opposite polarity may damage the I/O devices. Especially check the wiring to prevent the speed setting potentiometer from being connected incorrectly to short circuit the terminals 10E and 5.

32

The converter unit and the inverter are correctly connected.

Make sure that terminal P/+ of the converter unit and terminal P/+ of the inverter, and terminal N/- of the converter unit and terminal N- of the inverter are correctly connected. Connecting the opposite polarity of terminals N/- and P/+ will damage the inverter. Also, do not install an MCCB across terminals P/+ and N/- (across terminals P and P/+ or across N and N/-).

Always connect terminal RDA of the converter unit and terminal MRS (X10) of the inverter, and terminal SE of the converter unit and terminal SD (terminal PC for source logic) of the inverter. Not connecting these terminals may damage the converter unit.

26

When using the electronic bypass operation, electrical and mechanical interlocks are provided between the electronic bypass contactors MC1 and MC2.

When using a switching circuit as shown below, chattering due to mis- configured sequence or arc generated at switching may allow undesirable current to flow in and damage the inverter. Mis-wiring may also damage the inverter. (The commercial power supply operation is not available with PM motors.)

If switching to the commercial power supply operation while a failure such as an output short circuit has occurred between the magnetic contactor MC2 and the motor, the damage may further spread. If a failure has occurred between the MC2 and the motor, a protection circuit such as using the OH signal input must be provided.

-

Precautions are taken for power restoration after a power failure.

If the machine must not be restarted when power is restored after a power failure, provide an MC in the converter unit's input side and also make up a sequence which will not switch ON the start signal. If the start signal (start switch) remains ON after a power failure, the inverter will automatically restart as soon as the power is restored.

-

A magnetic contactor (MC) is installed on the converter unit's input side.

On the converter unit's input side, connect an MC for the following purposes: To disconnect the inverter and the converter unit from the power supply at activation of a protective function or at malfunctioning of the driving system (emergency stop, etc.).

To prevent any accident due to an automatic restart at power restoration after an inverter stop made by a power failure.

To separate the inverter and the converter unit from the power supply to ensure safe maintenance and inspection work.

If using an MC for emergency stop during operation, select an MC regarding the converter unit input side current as JEM 1038-AC-3 class rated current.

52

The magnetic contactor on the inverter's output side is properly handled.

Switch the magnetic contactor between the inverter and motor only when both the inverter and motor are at a stop.

52

When using a PM motor, a low- voltage manual contactor is installed on the inverter's output side.

A PM motor is a synchronous motor with high-performance magnets embedded inside. High-voltage is generated at the motor terminals while the motor is running even after the inverter power is turned OFF. In an application, such as fan and blower, where the motor is driven by the load, a low-voltage manual contactor must be connected at the inverter's output side, and wiring and inspection must be performed while the contactor is open. Otherwise you may get an electric shock.

52

EMC precautions are taken for the frequency setting signals.

If electromagnetic noise generated from the inverter and the converter unit causes frequency setting signal to fluctuate and the motor rotation speed to be unstable when changing the motor speed with analog signals, the following precautions are effective: Do not run the signal cables and power cables (inverter and converter unit I/O cables) in parallel with each other and do not bundle them.

Run signal cables as far away as possible from power cables (inverter and converter I/O cables).

Use shielded cables. Install a ferrite core on the signal cable.

PRECAUTIONS FOR USE OF THE INVERTER 55

Checklist before starting operation

A countermeasure is provided for an overload operation.

When performing frequent starts/stops by the inverter, rise/fall in the temperature of the transistor element of the inverter will repeat due to a repeated flow of large current, shortening the life from thermal fatigue. Since thermal fatigue is related to the amount of current, the life can be increased by reducing current at locked condition, starting current, etc. Reducing current may extend the service life but may also cause torque shortage, which leads to a start failure. Adding a margin to the current can eliminate such a condition. For an induction motor, use the inverter and the converter unit of a higher capacity (up to two ranks). For a PM motor, use the inverter and the converter unit, and PM motor of higher capacities.

56 PRECAUTIONS FOR USE OF THE INVERTER

Failsafe system which uses the inverter

3

3.7 Failsafe system which uses the inverter When a fault is detected by the protective function, the protective function is activated to output a fault signal. However, a fault

signal may not be output at an inverter's fault occurrence when the detection circuit or output circuit fails, etc. Although

Mitsubishi Electric assures the best quality products, provide an interlock which uses inverter status output signals to prevent

accidents such as damage to the machine when the inverter fails for some reason. Also at the same time consider the system

configuration where a failsafe from outside the inverter, without using the inverter, is enabled even if the inverter fails.

Interlock method which uses the inverter status output signals By combining the inverter output signals to provide an interlock as shown below, an inverter failure can be detected.

No. Interlock method Check method Used signals

a Inverter protective function operation

Operation check of an alarm contact. Circuit error detection by negative logic.

Fault (ALM) signal

b Inverter operating status Operation ready signal check. Inverter operation ready (RY) signal

c Inverter running status Logic check of the start signal and running signal. Start (STF/STR) signal Inverter running (RUN) signal

d Inverter running status Logic check of the start signal and output current. Start (STF/STR) signal Output current detection (Y12) signal

(a) Checking by the output of the inverter fault signal

When the inverter's protective function is activated and

the inverter trips, the Fault (ALM) signal is output. (The

ALM signal is assigned to terminal A1B1C1 in the initial

setting).

With this signal, check that the inverter operates

properly.

In addition, negative logic can be set. (ON when the

inverter is normal, OFF when the fault occurs.)

(b) Checking the inverter operating status by the inverter

operation ready completion signal

The Inverter operation ready (RY) signal is output when

the inverter power is ON and the inverter becomes

operative.

Check if the RY signal is output after powering ON the

inverter.

(c) Checking the inverter operating status by the start signal

input to the inverter and inverter running signal

The Inverter running (RUN) signal is output when the

inverter is running. (The RUN signal is assigned to

terminal RUN in the initial setting.)

Check if the Y12 signal is being output while inputting a

start signal to the inverter. (The STF signal is a forward

rotation signal, and the STR signal is a reverse rotation

signal.) Even after the start signal is turned OFF, the

RUN signal is kept output until the inverter makes the

motor to decelerate and to stop. For the logic check,

configure a sequence considering the inverter's

deceleration time.

PRECAUTIONS FOR USE OF THE INVERTER 57

Failsafe system which uses the inverter

NOTE Changing the terminal assignment using Pr.190 and Pr.196 (Output terminal function selection) may affect the other

functions. Set parameters after confirming the function of each terminal.

For the details of the parameters and signals, refer to the Instruction Manual (Detailed) of the FR-F860.

Backup method outside the inverter Even if the interlock is provided by the inverter status signal, enough failsafe is not ensured depending on the failure status of

the inverter itself. For example, if an inverter CPU fails in a system interlocked with the inverter's fault, STF/STR, and RUN

signals, no fault signal will be output and the RUN signal will be kept ON because the inverter CPU is down.

Provide a speed detector to detect the motor speed and current detector to detect the motor current and consider the backup

system such as performing a check as below according to the level of importance of the system.

(a) Start signal and actual operation check

Check the motor running and motor current while the start signal is input to the inverter by comparing the start signal to

the inverter and detected speed of the speed detector or detected current of the current detector. Note that the current

is flowing through the motor while the motor coasts to stop, even after the inverter's start signal is turned OFF. For the

logic check, configure a sequence considering the inverter's deceleration time. In addition, it is recommended to check

the three-phase current when using the current detector.

(b) Command speed and actual operation check

Check for a gap between the actual speed and commanded speed by comparing the inverter's speed command and

the speed detected by the speed detector.

(d) Checking the motor operating status by the start signal input to the inverter and inverter output current detection signal

The Output current detection (Y12) signal is output when the inverter operates and current flows into the motor.

Check if the Y12 signal is being output while inputting a start signal to the inverter. (The STF signal is a forward rotation

signal, and the STR signal is a reverse rotation signal.) The Y12 signal is initially set to be output at 110% rated inverter

current. Adjust the level to around 20% using no load current of the motor as reference with Pr.150 Output current detection level. Like the Inverter running (RUN) signal, even after the start signal is turned OFF, the Y12 signal is kept output until the

inverter stops the output to a decelerating motor. For the logic check, configure a sequence considering the inverter's

deceleration time.

When using various signals, assign the functions to Pr.190 and Pr.196 (Output terminal function selection) referring to the

table on the left.

Inverter fault and indications

60 PROTECTIVE FUNCTIONS

4.1 Inverter fault and indications When a fault occurs in the inverter, a protective function is automatically activated to shut off the inverter output and show

an indication on the operation panel of the inverter.

When any fault occurs, take an appropriate corrective action, then reset the inverter, and resume the operation. Restarting

the operation without a reset may break or damage the inverter.

When a protective function is activated, note the following points.

Inverter fault or alarm indications are categorized as below.

NOTE For the details of fault displays and other malfunctions, refer to the Instruction Manual (Detailed) of the FR-F860.

The past eight faults can be displayed on the operation panel. (Fault history) (For the operation, refer to the operation panel

or the parameter unit Instruction Manual.)

4.2 Reset method for the protective functions Reset the inverter by performing any of the following operations. Note that the accumulated heat value of the electronic

thermal relay function and the number of retries are cleared (erased) by resetting the inverter.

The inverter recovers about 1 s after the reset is released.

NOTE OFF status of the start signal must be confirmed before resetting the inverter fault. Resetting an inverter fault with the start

signal ON restarts the motor suddenly.

Item Description

5.1.5 Cleaning Always run the inverter in a clean status.

When cleaning the inverter, gently wipe dirty areas with a soft cloth immersed in neutral detergent or ethanol.

NOTE Do not use solvent, such as acetone, benzene, toluene and alcohol, as these will cause the inverter surface paint to peel off.

The display, etc. of the operation panel and parameter unit are vulnerable to detergent and alcohol. Therefore, avoid using

them for cleaning.

5.1.6 Replacement of parts The inverter consists of many electronic parts such as semiconductor devices.

The following parts may deteriorate with age because of their structures or physical characteristics, leading to reduced

performance or fault of the inverter. For preventive maintenance, the parts must be replaced periodically.

Use the life check function as a guidance of parts replacement.

Estimated lifespan for when the yearly average surrounding air temperature is 40C.

(without corrosive gas, flammable gas, oil mist, dust and dirt etc.)

Output current (80% of the inverter rating)

NOTE For parts replacement, contact the nearest Mitsubishi Electric FA center.

Inverter parts life display The inverter diagnoses the control circuit capacitor and the cooling fan by itself, and estimates their lives.

The self-diagnostic warning is output when the life span of each part is near its end. It gives an indication of replacement time.

The life warning output can be used as a guideline for life judgment.

NOTE Refer to the Instruction Manual (Detailed) of the FR-F860 to perform the life check of the inverter parts.

Parts Judgment level Control circuit capacitor Estimated remaining life 10%

Cooling fan Not more than the specified speed

PRECAUTIONS FOR MAINTENANCE AND INSPECTION 67

Inspection item

Replacement procedure of the cooling fan The replacement interval of the cooling fan used for cooling the parts generating heat such as the main circuit semiconductor

is greatly affected by the surrounding air temperature. When unusual noise and/or vibration are noticed during inspection, the

cooling fan must be replaced immediately.

Removal 1) Remove the fan cover fixing screws, and remove the fan cover.

2) Disconnect the fan connector and remove the fan block.

3) Remove the fan fixing screws, and remove the fan.

The number of cooling fans differs according to the inverter capacity.

Reinstallation 1) Before installing the new fan, check the orientation of the fan to be sure that the "AIR FLOW" arrow printed on the side

of the fan points upward.

2) For reconnection of the fan, refer to the above figure.

NOTE Installing the fan in the opposite direction of air flow can cause the inverter life to be shorter.

Prevent the cable from being caught when installing a fan.

Switch the power OFF before replacing fans. Since the inverter circuits are charged with voltage even after power OFF,

replace fans only when the inverter cover is on the inverter to prevent an electric shock accident.

Smoothing capacitors A large-capacity aluminum electrolytic capacitor is used for smoothing in the DC section of the main circuit, and an aluminum

electrolytic capacitor is used for stabilizing the control power in the control circuit. Adverse effects from ripple currents

deteriorate capacitors. Replacement intervals of capacitors vary greatly with surrounding temperatures and operating

conditions. Replace them roughly every 10 years when used in normal air-conditioned environments.

Inspecting the product visually:

Case: Check that the sides and bottom of the capacitor have not ruptured.

Rubber seal: Check for any noticeable bulging or severe cracks.

Check for external cracks, discoloration, leakage, etc. It is assumed that the capacitor has reached the end of its life when

its capacity has dropped below 80% of its rated capacity.

NOTE The inverter diagnoses the control circuit capacitor by itself and can estimate its remaining life. (Refer to the FR-F860

Instruction Manual (Detailed).)

Relay output terminals The contacts of relays deteriorate over time. To prevent faults from occurring, relays must be replaced when they have

reached the maximum of switching operations (switching life).

The control terminal block must be replaced (refer to page 69) in case of failure of either relay connected to the relay output

terminals A1, B1, and C1, or A2, B2, and C2. (After replacing the control terminal block, connect the jumper connector to

the correct position in accordance with the control logic of input signals. (Refer to page 36.))

Main circuit fuse A fuse is used inside the inverter. Replacement intervals of fuses vary with surrounding temperatures and operating

conditions. Replace them roughly every 10 years when used in normal air-conditioned environments.

5.1.7 Removal and reinstallation of the control circuit terminal block

The FR-F800 series inverter has a removable control circuit terminal block, which can be replaced with a new one or a control

terminal option.

Removal and reinstallation 1) Loosen the two mounting screws at the both side of the control circuit terminal block. (These screws cannot be removed.)

Slide down the control circuit terminal block to remove it.

Loosen the screws

2) Be careful not to bend the pins of the inverter's control circuit connector, reinstall the control circuit terminal block and fix it

with the mounting screws.

NOTE Before starting inverter replacement, switch power OFF, wait for at least 10 minutes, and then check the voltage with a tester

and such to ensure safety.

Removal and reinstallation precautions Precautions to be taken when removing or reinstalling the control circuit terminal block are shown below.

Observe the following precautions and handle the inverter properly to avoid malfunctions or failures.

To remove or reinstall the control circuit terminal block, keep it upright so that it is parallel with the inverter.

To install the control circuit terminal block, slide it upward so that the tongues on the inverter slot into the grooves on the

terminal block.

Check that the terminal block is parallel to the inverter and the pins on the inverter control circuit connector are not bent.

After checking proper connection, fix the terminal block in place with two screws.

NOTE Do not tilt the terminal block while tightening the screws or removing it from the inverter. (Otherwise, stress applied to the

control circuit terminal block or the control circuit connector may damage the pins.)

After replacing the control terminal block, connect the jumper connector to the correct position in accordance with the control

logic of input signals. (Refer to page 36.)

Fasten the screws.

5.2 Measurement of main circuit voltages, currents and powers

Since the voltages and currents on the inverter power supply and output sides include harmonics, measurement data

depends on the instruments used and circuits measured.

When instruments for commercial frequency are used for measurement, measure the following circuits with the instruments

given on the next page.

NOTE When installing meters etc. on the inverter output side

When the wiring length between the inverter and the motor is large, the meters and CTs may generate heat due to line-to-line

leakage current. Therefore, choose the equipment which has enough allowance for the current rating.

To measure and display the output voltage and output current of the inverter, it is recommended to use terminal AM and CA

output functions of the inverter.

Measurement of main circuit voltages, currents and powers

Measuring points and instruments

Use an FFT to measure the output voltage accurately. A tester or general measuring instrument cannot measure accurately.

When the carrier frequency exceeds 5 kHz, do not use this instrument since using it may increase eddy current losses produced in metal parts

inside the instrument, leading to burnout. In this case, use an approximate-effective value type.

72 PRECAUTIONS FOR MAINTENANCE AND INSPECTION

Measurement of main circuit voltages, currents and powers

5

5.2.1 Measurement of powers Use a digital power meter (for inverter) for the input side of the converter unit (FR-CC2-C) and the output side of the inverter.

5.2.2 Measurement of voltages Converter unit (FR-CC2-C) input side Use a digital power meter for inverters for the input side voltage.

Inverter output side Always use a digital power meter for inverter for measurement as the output side voltage has a PWM-controlled rectangular

wave. The value monitored on the operation panel is the inverter-controlled voltage itself. Hence, that value is accurate and it

is recommended to monitor values (analog output) using the operation panel.

5.2.3 Measurement of currents Use digital power meters (for converter) for the both of inverter input and output side.

Since current on the converter unit input side tends to be unbalanced, measurement of three phases is recommended.

Correct value cannot be obtained by measuring only one or two phases. On the other hand, the unbalanced ratio of each

phase of the output side current should be within 10%.

The inverter output current can be monitored on the operation panel. The value monitored on the operation panel is accurate

if the output frequency varies, and it is recommended to monitor values (provide analog output) using the operation panel.

Examples of measured value differences produced by different measuring meters are shown below.

5.2.4 Example of measuring converter unit (FR-CC2-C) input power factor

Calculate using effective power and apparent power. A power-factor meter cannot indicate an exact value.

5.2.5 Measurement of converter output voltage (across terminals P and N)

The output voltage of the converter is output across terminals P and N, and can be measured with a voltmeter such as a

digital multimeter. Although the voltage varies according to the power supply voltage, approximately 800 to 900 V is output

when no load is connected and voltage decreases during driving load operation.

When energy is regenerated from the motor during deceleration, for example, the converter output voltage rises to nearly

1100 to 1300 V maximum.

5.2.6 Measurement of inverter output frequency In the initial setting, a pulse train proportional to the output frequency is output across the analog current output terminals CA

and 5 of the inverter. Measure the current using a tester.

For detailed specifications of the analog current output terminal CA, refer to the Instruction Manual (Detailed) of the FR-F860.

5.2.7 Insulation resistance test using megger For the inverter and the converter unit (FR-CC2-C), conduct the insulation resistance test on the main circuit only as shown

below and do not perform the test on the control circuit. (Use a 500 VDC megger.)

NOTE Before performing the insulation resistance test on the external circuit, disconnect the cables from all terminals of the inverter

and the converter unit so that the test voltage is not applied to the inverter and the converter unit.

For the continuity test of the control circuit, use a tester (high resistance range) and do not use the megger or buzzer.

6.1 Inverter rating Inverter

The applicable motor capacity indicated is the maximum capacity applicable for use of the 4-pole standard motor.

The rated output capacity indicated assumes that the output voltage is 575 V.

When an operation is performed with the carrier frequency set to 3 kHz or more, and the inverter output current reaches the value indicated in

the parenthesis, the carries frequency is automatically lowered. The motor noise becomes louder accordingly.

The % value of the overload current rating indicated is the ratio of the overload current to the inverter's rated output current. For repeated duty,

allow time for the inverter and motor to return to or below the temperatures under 100% load.

The maximum output voltage does not exceed the power supply voltage. The maximum output voltage can be changed within the setting range.

However, the maximum point of the voltage waveform at the inverter output side is the power supply voltage multiplied by about .

APPENDIX 83

NOTE The internal accumulated heat value of the electronic thermal relay function is reset by inverter power reset and reset signal

input. Avoid unnecessary reset and power-OFF.

Install an external thermal relay (OCR) between the inverter and motors to operate several motors, a multi-pole motor or a

dedicated motor with one inverter. Note that the current indicated on the motor rating plate is affected by the line-to-line

leakage current (refer to the FR-F860 Instruction Manual (Detailed)) when selecting the setting for an external thermal relay.

The cooling effect of the motor drops during low-speed operation. Use a thermal protector or a motor with built-in thermistor.

When the difference between the inverter and motor capacities is large and the setting is small, the protective characteristics

of the electronic thermal relay function will be deteriorated. In such case, use an external thermal relay.

A dedicated motor cannot be protected by an electronic thermal O/L relay. Use an external thermal relay.

Motor over temperature sensing is not provided by the drive.

2 Main circuit capacitor residual-life estimation function

Even when the power supply cannot be turned OFF, the remaining life of the main circuit capacitor can be estimated

without stopping the operation. Note that the remaining life of the main circuit capacitor estimated by this function is

theoretical, and should be used as a guideline only.

*1 Valid values (read only) for separated converter type inverters are "0, 1, 4, and 5". The setting range (reading only) for IP55 compatible

modes is "0 to 63".

*2 The setting is available only for standard models and IP55 compatible models.

Display estimated main circuit capacitor residual life (Pr.506) The estimated residual life of the main circuit capacitor is displayed in Pr.506.

The remaining life of the main circuit capacitor is calculated from the energization time and the inverter output power (100% =

Start of service life). When the remaining life of the main circuit capacitor falls below 10%, bit 5 of Pr.255 Life alarm status

display turns ON and a warning is output by the Y90 signal.

Life alarm display and signal output (Y90 signal, Pr.255)

Power no longer needs to be turned OFF for the warning signal (Y90) to be output when using the main circuit

residual-life estimation function.

Whether or not the parts of the control circuit capacitor, main circuit capacitor, cooling fan, inrush current limit circuit or internal

air circulation fans have reached the life alarm output level can be checked with Pr.255 Life alarm status display and the Life

alarm (Y90) signal. (Internal air circulation fans are equipped with IP55 compatible models.)

The Life alarm (Y90) signal turns ON when either the control circuit capacitor life, main circuit capacitor life, cooling fan life,

inrush current limit circuit life, internal air circulation fan life or the estimated residual life of the main circuit capacitor reaches

the level set to output the life alarm.

For the terminal used for the Y90 signal, set "90" (positive logic) or "190" (negative logic) in any of Pr.190 to Pr.196 (Output

terminal function selection).

NOTE When using an option (FR-A8AY, FR-A8AR, FR-A8NC, FR-A8NCE), the life alarm for the Control circuit capacitor

life (Y86 signal), Main circuit capacitor life (Y87 signal), Cooling fan life (Y88 signal), Inrush current limit circuit life

(Y89 signal), and the estimated residual-life of the Main circuit capacitor (Y248 signal) can be output individually.

Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the

other functions. Set parameters after confirming the function of each terminal.

3 Reset selection after inverter faults are cleared (Pr.349, N241)

When the communication option is specified for the command source in Network operation mode, it is possible to select

whether the inverter is reset after the "Fault reset" command is executed. (Only when the HMS network option is installed.)

1 Direct multi-speed operation

When the RLF (RLR) signal is input, the operation is the same as the one when the STF (STR) signal and RL signal

are input.

Input terminal function assignment Use Pr.178 to Pr.189 to set the functions of the input terminals.

Refer to the following table and set the parameters.

Direct multi-speed setting While the RLF or RLR signal is input, the operation is according to Pr.6 Multi-speed setting (low-speed). The rotation is

forward while the RLF signal is input, and the rotation is reverse while the RLR signal is input.

NOTE The Pr.6 setting should be equal to or higher than the Pr.13 Starting frequency setting.

To assign the RLF and RLR signals to input terminals, set "128 (RLF)" and "129 (RLR)" in any two parameters from

Pr.178 to Pr.189 (Input terminal function selection).

The direct multi-speed operation is enabled only when the inverter operates in External operation mode.

When the RLR or STR signal is input while the RLF signal is input, the motor is decelerated to stop.

When the RLF or STF signal is input while the RLR signal is input, the motor is decelerated to stop.

When Pr.59 Remote function selection "0", the RLF signal is used as the STF signal, and the RLR signal is used

as the STR signal.

When the stop-on-contact function is enabled, the RLF signal is used as the STF signal, and the RLR signal is used

as the STR signal.

When the RLF or RLR signal is turned ON to enable the direct multi-speed operation, the setting of Pr.250 Stop

selection and the STP (STOP) signal are disabled.

The deterioration degree of the main circuit capacitor is displayed in Pr.258.

With the main circuit capacitor capacity at factory shipment as 100%, the capacitor life is displayed in Pr.258 every time

measurement is made. When the measured value falls to 85% or lower, bit 1 of Pr.255 is turned ON (set to 1) and the Y90

signal is also output as an alert.

Measure the capacitor capacity according to the following procedure and check the deterioration degree of the capacitor

capacity.

1. Check that the motor is connected and at a stop.

2. Set "1, 11" (measuring start) in Pr.259.

3. Switch the power OFF. The inverter applies DC voltage to the motor to measure the capacitor capacity

while the inverter is OFF.

4. After confirming that the power lamp is OFF, turn ON the power again.

5. Check that "3, 13" (measurement complete) is set in Pr.259, read Pr.258, and check the deterioration

degree of the main circuit capacitor.

NOTE When the main circuit capacitor life is measured under the following conditions, "forced end" (Pr.259 = "8, 18"), or

"measurement error" (Pr.259 = "9, 19") may occur, or the status may remain in "measurement start" (Pr.259 = "1,

11"). To perform measurement, first eliminate the following conditions. Under the following conditions, even if

"measurement complete" (Pr.259 = "3, 13") is reached, measurement cannot be performed correctly.

Operation environment: Surrounding air temperature (annual average of 40C (free from corrosive gas, flammable

gas, oil mist, dust and dirt)).

Output current: 80% of the inverter rating

Since repeated inrush currents at power ON will shorten the life of the converter circuit, frequent starts and stops of

the magnetic contactor must be avoided.

- The power supply is switched ON during measurement.

- The motor is not connected to the inverter.

- The motor is running (coasting).

- The motor capacity is smaller than the inverter capacity by two ranks or more.

- The inverter output is shut off or a fault occurred while the power was OFF.

- The inverter output is shut off with the MRS signal.

- The start command is given while measuring.

- The applied motor setting is incorrect.

WARNING When measuring the main circuit capacitor capacity (Pr.259 = "1, 11"), the DC voltage is applied to the motor for about 1

second at power OFF. Never touch the motor terminal, etc. right after powering OFF to prevent an electric shock.

5 Load characteristics fault detection

This section describes how to set the load characteristics reference for the existing load characteristics fault detection

function. The following shows the procedure to set the load characteristics reference manually.

Setting the load characteristics reference manually (Pr.1481 to Pr.1485)

Set Pr.1480 Load characteristics measurement mode = "0" (initial value).

Set Pr.1486 and Pr.1487 to specify the frequency band for the measurement, and calculate the frequency as the load

characteristics reference (f2 to f4) using the following table.

Start the inverter operation, and set Pr.1481 = "8888" during operation at the frequency of the load characteristics reference 1

(f1). The load status at that point is set in Pr.1481 (only when the set frequency is within 2 Hz of the frequency of the

measurement point, and the SU signal is ON).

Set load references in Pr.1482 to Pr.1485 in the same way as Pr.1481.

NOTE When inputting values in Pr.1481 to Pr.1485 directly, input the load meter monitored values at the frequency of each

load characteristics reference.

2 Inverter parts life display The degree of deterioration of the control circuit capacitor, main circuit capacitor, cooling fan, inrush current limit circuit, and relay contacts of terminals A, B, and C can be diagnosed on the monitor. When the life span of each part is near its end, the self-diagnostic warning is output to prevent a fault. (Use the life check of this function as a guideline only, since the life span of each part except for the main circuit capacitor is calculated theoretically.)

*1 The setting range (read-only) differs depending on the inverter model (standard model, separate converter type, or IP55 compatible model).

Life alarm display and signal output (Y90 signal, Pr.255)

In the life diagnosis of the main circuit capacitor, the alarm signal (Y90) is not output unless measurement by turning OFF the power supply is performed.

Pr.255 Life alarm status display and the Life alarm (Y90) signal can be used to check whether or not the life alarm output level is reached for the following parts: the control circuit capacitor, main circuit capacitor, cooling fan, inrush current limit circuit, relay contacts of terminals A, B, and C, and internal air circulation fan. (Internal air circulation fans are equipped with IP55 compatible models.)

When the parts have reached the life alarm output level, the corresponding bits of Pr.255 turns ON. The ON/OFF state of the bits can be checked with Pr.255. The following table shows examples.

The Life alarm (Y90) signal turns ON when the life alarm output level is reached for either of the following: the control circuit capacitor life, main circuit capacitor life, cooling fan life, inrush current limit circuit life, internal air circulation fan life, estimated residual-life of the main circuit capacitor, ABC1 relay contact life, or ABC2 relay contact life.

For the terminal used for the Y90 signal, set "90" (positive logic) or "190" (negative logic) in any of Pr.190 to Pr.196 (Output terminal function selection).

NOTE When using an option (FR-A8AY, FR-A8AR, FR-A8NC, FR-A8NCE, or FR-A8NCG), warning signals can be output

individually: Control circuit capacitor life (Y86) signal, Main circuit capacitor life (Y87) signal, Cooling fan life (Y88) signal, Inrush current limit circuit life (Y89) signal, Estimated residual-life of main circuit capacitor (Y248) signal, ABC1 relay contact life (Y249) signal, and ABC2 relay contact life (Y250) signal.

Changing the terminal assignment using Pr.190 to Pr.196 (Output terminal function selection) may affect the other functions. Set parameters after confirming the function of each terminal.

Life display of the relay contacts of terminals A, B, and C (Pr.507, Pr.508)

The degree of deterioration of the relay contacts of terminals A1, B1, and C1 is displayed in Pr.507, and that for terminals A2, B2, and C2 is displayed in Pr.508.

The number of times the contacts of relay turn ON is counted down from 100% (0 time) by 1% (500 times). When the counter reaches 10% (45,000 times), bit 6 or bit 7 of Pr.255 turns ON and a warning is output by the Y90 signal.

Any value can be set in Pr.507 and Pr.508. After replacement of the control circuit terminal block or installation of a control terminal option, set Pr.507 and Pr.508 again.

FR-F800 Series Instruction Manual Supplement

1 Internal storage device fault (E.PE6) The operation of the storage device in the inverter can be checked. If a data fault occurs in the storage device in the inverter, the protective function (E.PE6) is activated. When the read value of Pr.890 is "7" or smaller, an inverter reset after All parameter clear can return the operation to normal. (The parameters that had been changed before All parameter clear must be set again.)

*1 For example, when parameter clear, All parameter clear, Parameter copy, or offline auto tuning is performed in the inverter, or when parameter batch write is performed in FR Configurator2.

NOTE "E.PE6" does not activate the retry function. "E.PE6" outputs the Fault output 3 (Y91) signal. "E.PE6" turns OFF the Safety monitor output (SAFE) signal. "E.PE6" is not cleared by turning ON the Fault clear (X51) signal. "E.PE6" is not activated during emergency drive operation. The communication data code for "E.PE6" is 172 (HAC).

Checking faulty area in the internal storage device When E.PE6 occurs, faulty area in the internal storage device can be checked by reading Pr.890.

Use the read value of Pr.890 to check the faulty area. The following table shows faulty areas indicated by the read value of Pr.890. Some read values indicate that there are multiple

faulty areas. (For example, the read value "7" indicates that all the areas described in No. 1 to No. 3 are faulty.)

indication Fault

Name Internal storage device fault

Description This protective function is activated by an inverter reset if writing data fails due to power-OFF or a data fault occurs in the storage device during parameter operations*1.

Check point Check if the power was turned OFF during parameter operations.

Corrective action

Check the power supply or the devices on the power system to check that the devices have no fault. When E.PE6 occurs due to power-OFF during parameter operations:

Check the read value of Pr.890. When the value is "7" or smaller, perform All parameter clear and then an inverter reset. The parameters that had been changed before All parameter clear must be set again.

When E.PE6 occurs due to other reason (such as turning OFF/ON the power or an inverter reset): Contact your sales representative.

2 PID upper/lower limit pre-warning (Pr.1346, Pr.1370 to Pr.1373)

Pr.1346 PID lower limit operation detection time is added. Detection time for PID upper/lower limit pre-warning can be set separately.

The set point can be changed to suppress increases of the measured value before PID upper limit (FUP) or PID lower limit (FDN) is detected.

When the measured value reaches and remains at the pre-warning level set in Pr.1371 PID upper/lower limit pre-warning level range for the time set in Pr.1370 Detection time for PID limiting operation, the PID upper/ lower limit pre-warning (Y219) signal or the Second PID upper/lower limit pre-warning (Y220) signal is output. Also, the set point is changed by the amount set in Pr.1372 PID measured value control set point change amount.

To set the detection time for upper and lower limits separately, set Pr.1346 PID lower limit operation detection time.

Set the rate (%/s) in Pr.1373 PID measured value control set point change rate for changing the set point by the Pr.1372 setting value. When the measured value falls within the normal range, the set point returns to its original value.

For the Y219 and Y220 signals, assign the functions to output terminals using the Pr.190 to Pr.196 (Output terminal function selection).
